Reducing Speed While Using Cruise Control There are two ways to reduce your speed while using cruise control: Using Cruise Control on Hills How well the cruise control will work on hills depends upon the speed and load of the vehicle, and the steepness of the hills. When going up steep hills, you may have to step on the accelerator pedal to maintain the vehicle's speed. When going downhill, you may have to brake or shift to a lower gear to keep the vehicle's speed down. Of course, applying the brake takes the vehicle out of cruise control. Many drivers find this to be too much trouble and do not use cruise control on steep hills. • Press the SET − button until you reach the lower speed you want, then release it. • To slow down in very small amounts, briefly press the SET − button. Each time you do this, you will go about 1 mph (1.6 km/h) slower. Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase the vehicle's speed. When you take your foot off the pedal, the vehicle will slow down to the cruise control speed you set earlier. Ending Cruise Control To end a cruise control session, step lightly on the brake pedal. Stepping on the brake will end the current cruise control session only. Press the cruise on/off button to turn off the system completely. Erasing Speed Memory When you turn off the cruise control or the ignition, your cruise control set speed memory is erased. 3-12
